The Journey of Zerobaseone
Formation and Debut (2023)
The group was established following the conclusion of Boys Planet, where the final nine members were selected to form a new musical unit. They officially debuted on July 10, 2023, with the album Youth in the Shade. The group's impact was immediate; they surpassed 1.08 million pre-orders, making them a "million seller" right out of the gate.
They followed this success with their second mini-album, Melting Point, in November 2023, which further solidified their status by selling over 2.1 million copies in its first week.

International Expansion and Growth (2024)
In 2024, Zerobaseone expanded their reach into the Japanese market. Their Japanese debut saw them breaking records as the first foreign artist to rank first on the Oricon charts with a first-week sale exceeding 300,000 copies. This year also marked their first major concert tour, Timeless World.

Evolution and Lineup Changes (2025–2026)
The years 2025 and 2026 brought significant changes to the group's trajectory. After a prolific 2025—which included the release of the EP Blue Paradise and the first full-length album—the group underwent a major transition. In early 2026, it was announced that four members would be leaving the group.
Following this departure, Zerobaseone reshuffled into a quintet (a five-member group). Despite the change, the group continued their activities, releasing the 6th mini-album, Ascend-, in May 2026.
